Galvanic Corrosion is an electrochemical process resulting from one metal corroding to another when both metals are in electrical contact, in the presence of an electrolyte. When two dissimilar conducting materials in electrical contact with each other are exposed to an electrolyte, a current flow from one to the other. The Galvanic Corrosion is that part of the corrosion that occurs at the anodic member of such a couple and is directly related to the galvanic current by Faraday’s law. Where the more noble metal is protected the more active metal tends to corrode.
